Documentación de las funciones

int xsltCheckRead	(	xsltSecurityPrefsPtr	sec,
		xsltTransformContextPtr	ctxt,
		const xmlChar *	URL
	)

xsltCheckRead: : the security options : an XSLT transformation context : the resource to be read

Check if the resource is allowed to be read

Return 1 if read is allowed, 0 if not and -1 in case or error.

int xsltCheckWrite	(	xsltSecurityPrefsPtr	sec,
		xsltTransformContextPtr	ctxt,
		const xmlChar *	URL
	)

xsltCheckWrite: : the security options : an XSLT transformation context : the resource to be written

Check if the resource is allowed to be written, if necessary makes some preliminary work like creating directories

Return 1 if write is allowed, 0 if not and -1 in case or error.

void xsltFreeSecurityPrefs

(

xsltSecurityPrefsPtr

sec

)

xsltFreeSecurityPrefs: : the security block to free
